Title: Production of metal matrix composite
Inventor: KUBO MASAHIRO
IPC: C22C47/08
Filed: 1989-06-27
Abstract: PURPOSE:To improve adhesive strength between a reinforcement and a matrix metal by producing a composite material by using composite particles prepared by mixing fine pieces of metal and reinforcement by means of a high-energy ball mill. CONSTITUTION:At the time of producing a metal matrix composite in which particles and short fibers (including whiskers) are used as reinforcement and metal is used as matrix, fine pieces of metal and reinforcement or fine pieces of metal and fine pieces of metal oxide are mixed by means of a high-energy ball mill. For example, a powder mixture 10 consisting of SiC particles of 3mu average particle size and powdered Al alloy of 74mu average particle size in the prescribed ratio is charged together with balls 12 made of bearing steel into the vessel in a rotary ball mill 14 and rotated at 300rpm for 1hr by means of an impeller 18 and an agitator 20. A molten Al alloy 24 of 700 deg.C is agitated while adding the resulting composite particles 22 to this molten alloy 24, and then, this molten alloy is solidified, by which a metal matrix composite can be obtained. By this method, the reinforcement can be dispersed into the matrix metal more uniformly.

Filed: 1983-09-09
Abstract: PURPOSE:To eliminate the influence of remaining magnetism by providing an LRC series resonance circuit of an exciting coil and a capactor when driving a fan by an electromagnetic clutch to attenuate the stored energy of the coil. CONSTITUTION:A fan of an engine for a vehicle is driven by an electromagnetic clutch 11 which has two exciting coils 3a, 3b. A switch 13 is closed by the rise of coolant temperature of the engine to flow a current through a relay 121 to the coil 3a, and when the switch 13 is defective, a switch 14 is closed to operate the coil 3b. A capacitor 129 is added into a controller 12, and when the switch 13 is opened, the stored charge of the capacitor 129 is flowed reversely to the coil 3 to operate to cancel the remaining magnetism in the magnetic circuit of the electromagnetic clutch. Accordingly, the inoperation of the clutch due to the attracting defect of a disc can be eliminated.

Title: Method and apparatus for remote control of self-propelled press machine
Inventor: MIHIYAERU SHIYUTEFUEN
IPC: G08C25/00
Filed: 1993-07-05
Abstract: PURPOSE: To improve safety in operation by allocating a control beam and a near area beam within a receiving unit by means of an address so as to allocate to a channel respectively prohibited with respect to the other beam. CONSTITUTION: The receiving unit 11 is provided with an infrared eye A for receiving a beam sent back from diodes D1 to D3. This infrared eye A generates a current corresponding to the received beam. This current is filtered by a frequency filter F to exclude the faulty external line component of a frequency different from the near area beam and a far area beam in a control beam. The current outputted from the frequency filter F reaches a comparator K to inspect the intensity of the received beam cleared in current intensity when the intensity of a beam exceeds a threshold value. A current allowed to pass through operates the IC allocated to the current of IC circuits E1 to E3 by means of an address based on the address included in the current.

Title: Fin for air heat exchanger
Inventor: ITOU MASAAKI
IPC: F28F1/12
Filed: 1981-10-19
Abstract: PURPOSE:To obtain a fin having a high heat-transmitting performance and a small airflow resistance, by changing the relative positional relationship of louvers to the direction of the height of the fin. CONSTITUTION:The cutting-in direction of the louvers 7 is not perpendicular to folding lines 8 of the fin 6, but is parallel with end faces 66 of the fin 6. When such a fin 6 is formed into a corrugated fin by folding at the folding lines 8, the adjacent louvers 7 are cut in different directions. Namely, the relative positional relationship of the louver 7 varies in the direction of the height of the fin 6. Accordingly, each of the louvers 7 functions most effectively at cross section A-A and cross section C-C, while at cross section B-B, although the coefficient of heat transfer is low, the coefficient can be adjusted so that the airflow resistance is also small.

Abstract: PURPOSE:To obtain an inexpensive collimator element for an optical fiber which is easily mounted and manufactured by carrying out lens working on at least one end surface of a transparent rod with end surfaces having a larger diameter than the outgoing port of the optical fiber. CONSTITUTION:The lens part 1-2 of a Fresnel lens, etc., is formed on, for example, the projection end surface of a rod which is made of an optically transparent raw material and partially has a diameter nearly almost equal to the diameter of a connecting ferrule for the optical fiber 2 and the length of the rod is determined equivalently to the focal length of the formed lens in the rod, thus forming the collimating element 1. Consequently, a function which converts divergent luminous flux from the fiber 2 into parallel luminous flux substantially is obtained. Further, the optical fiber can be mounted without shifting in optical axis by a coupling connector such as an in-line connector 4. Consequently, the element 1 is easily mounted and demounted and manufactured at low cost.
